초록
Cardiovascular diseases (CVDs), including heart failure, pose a significant economic and health burden worldwide. Current treatment strategies for heart failure are greatly limited, in that they mainly mitigate symptoms or delay further progression. In contrast, therapies aimed at proactively preventing the onset of heart failure could greatly improve outcomes. Adiponectin is an adipocyte-derived hormone that confers an array of cardioprotective effects. It exerts anti-inflammatory effects, improves metabolic function, mitigates endothelial cell dysfunction, and reduce cardiomyocyte cell death. Furthermore, it has gained increasing attention for its ability to activate autophagy, a conserved cellular pathway that facilitates the degradation and recycling of cell components. The disruption of autophagy has been linked to CVDs including heart failure. Additionally, growing evidence also points to specific forms of autophagy, namely mitophagy and lipophagy, as crucial adaptive responses in protection against CVDs. The protective effects of adiponectin, autophagy, mitophagy, and lipophagy against CVDs along with potential therapeutic implications will be discussed.
